Abstract

An image processing method comprising a step of extracting a plurality of images, different in depth, of a 3-D object over a plurality of angles, a binarizing step of deleting the portion of a gray level range that has very few object components out of the plurality of images obtained by the extracting step, re-mapping the other portions into a specified gray level range, and binarizing the resultant portions, and a step of building the 3-D image of the 3-D object based on the images binarized by the binarizing step.
